Specification of Letters Patent.

Patented Nov. 29, 1910.

Application fihd September 27., 1909. Serial No. 519,826.

To all whom it may concern: Be it knownthat I, PATRICK J. MoRoNEY, a subject of the King of Great Britain and Ireland, residing inPhiladelphia, Pennsylvania, have invented certain Improvements in Cap-Spinning Machines, of which the following is a specification.

The main object of my invention is to so construct a cap spinning machine that the spindles can be placed in operative position close to the draft rolls, so'that a comparatively short staple fiber can be spun, as well as fiber of long staple.

A further object of the invention is to so construct the machine that the entire upper spindle rail carrying the spindles and caps can be lowered so as to allow for the dofiing of the caps and bobbins without interfering with the draft rolls.

In the accompanying drawings :Figure 1, is a front view of sufficient of a cap spinning machine to illustrate my invention, the spindles being raised; Fig. 2, is a sectional view on the line 22, Fig. 1; Fig. 3, is a view similar to Fig. 1, with the upper spindle rail lowered; and Fig. 4, is a sec tional view on the line 41-4, Fig. 8.

A is the frame of the spinning machine, B is the lower spindle rail rigidly secured to the end frames A.

C is the upper spindle rail and c is the lifter plate. The ends of the rails C are ada ted tg vertical grooves a' in the frames K.

D, D are the spindles mounted in the usual manner and having the usual form of ca s d.

I) is the front bottom draft roll and E is the front top draft roll mounted so as to be located above the caps-when in the raised position, as shown in Figs. 1 and 2, but so located that when the spindle rail is lowered with the spindle and caps there will be sufficient space to allow for the ready removal of the caps.

F is the guide rail having arms 7 provided with eyes through which the yarn passes. These arms are preferably pivoted to the rail at f, so that they can be turned to one side out of line with the-caps to allow for the ready removal of the caps.

The upper spindle rail C may be raised and lowered in any manner desired. In the present instance I use two toggle links 6, b, one set of links being ivoted to the rail C I3 and both links being pivoted to a connect- 111g rod II at It. At the end is a rod H, pivoted to the last toggle and connected to the short arm 2' is an operating lever I. This locking the lever may be resorted to without departing from the essential features of the invention.

In order to counterbalance the rail C and its spindles, I use oneipr more counterbalance levers K which are pivoted at l; to

I brackets K secured to the fixed'rail B. One

arm of the counterbalance lever rests against the end of a post L secured to the rail C, and on the other end of the lever is an adjustable weight thus the rail C is counterbalanced and can be freely raised and lowered. I

The operation is as follows :-\Vhe n the spinning frame is running the rail C s in the raised position, as illustrated in Fig. 1, and the caps are comparatively close to the nip of the front rollers. they may be within three and one-ha inches, or even less, according to the design of the machine. The rail C is held in its raised position by the locked toggle mechanism described above. v

hen the bobbins are full the frame is stopped and the rail C is lowered by operating the lever I. The movement of the rail C is about equal to the traverse of the bobbins. This will bring the upper ends of the caps a sufiicient distance below the bite of the rolls E, E, so as to allow for the ready removal of the caps and the dofling of the spindles. In the event of the guides f being in the way, these guides can be turned on the pivots out of line with the caps. When the bobbins are placed on the splndles andthe caps adjusted in position, ,then the rail C is again moved to the raised position and locked. I i

. By the above construction it Wlll be seen that I am enabled to spin yarn of a comparatively short staple as well as long staple yarn.

I claim 1. The combination in a spinning machine, of draft rollers, a lifter plate, bobbins s pivoted to the rail 1 mounted thereon, a spindle rail, spindles In some instanci spindles and arranged to envelop the bobbins, the said lifter plate being capable of vertical movement during the winding of the bobbins, and means for raising and lowering the spindle rail.

The combination in a cap spinning. ma-

chine, ot' the supporting structure, draft rollers, a litter plate, bobbins rotatably mounted thereon, said lifter plate being capable of vertical movement, a movable spindle rail, spindles mounted thereon, a fixed rail, a toggle joint connecting the fixed rail and the spindle rail, a hand lever pivoted on the supporting structure, and a link connecting the hand lever to the toggle joint.

4. The combination in a cap spinning machine, of the supporting structure, draft rollers, a lifter plate, bobbins rotatably mounted thereon, a movable spindle rail, spindles mounted thereon, a fixed rail, a toggle joint connecting the fixed rail and the spindle rail, a hand lever pivoted to the supporting structure, a link conneetingthe hand lever to the toggle joint, and a counterbalance for the spindle rail.

5. The combination in a cap spinning maporting structure, a link connecting the hand lever to the toggle oint, and a counterbalance for the spindlerail, with means on said hand lever for automatically locking tions.

In testimony whereof, I have signed my name to this speclfication, 1n the presence of two subscribing witnesses.
